SPECIFICATION formingpart of Letters Patent No. 704,815, dated'July 15, 1902.

Application entrambe 11. 1900. Serin no. 39,529. or@ man.)

To all whom, it may concern:

Be it known that I, JULES EDOUARD `CHA- RON, manufacturer, a citizen of the Republic of France, residing at Montreuil sous Bois, 4:0 Boulevard de ll-ltel de Ville, Paris, inthe Republic of France, have invented certain new anduseful Improvements in Economic.

Figure 1 is au elevation, and fFig. 2 a ver tical section through the center of Fig. l, of one form of my invention; andFigs. 3 and 4 show in vertical section two other forms of my invention.

The lter for which I desire to obtain Letters Patent comprises, essentially, alayer of i glass wool or `Vspun-glass a, held, for example, between twovpieces of wire-gauze orperforated plates b vand c lwithin a metal casing. The latter ispreferably formed of two parts el c, put or soldered together, each being provided with a tube. -By means of a rubber connection]C onef of the saidftubes (that lettered g) can be connected to a conduit of water under pressure. The other tube h aords delivery of the filtered water. In order to maintain the grates h andfc and the filtering-layer easily in position, the iianges ij, in projection toward the interior,l are formed on the wall of the parts aand" d of the said casing. The grate c rests on the flange j. The glass wool is placed above the said grate and is pressed by the grate b, which rests on the liange t'. The secondpart, d of the casing, which fits onto the other part, prevents upward movement of the grate o. Alrubberq ring n, arrangedbetween thewall offthe casing and the spun glass, may be used to snp port the perforated partition b, and thus prevent the formation along the wall of tooeasy passages for the liquid. The parts d and e may be finally fixed together and a water-tight joint formed between the same by means of soldering. The rubber connection f may be so fixed within the tube g as to resist the pressure of the water.

The filter thus formed in a most economie manner can be tted by any unskilled person on any water-delivery cock. Itfgives a good discharge without requiring high pressure on the water, and it can be applied, for example, to the cock of a vessel in which the column of water is comparativelyfeeble.

The cleaning of the filter is easily and quickly operated by turning it upside down on the conduit or cock on which it is tted.

ln Fig. 3 I have shown a filter formed, as hereinbefore, of a casing in two parts d and e, provided, respectively, with the tubes g and 7i and of a iilteringpartition held within the said easingbetween two grates b and c, which rest against the flanges t andj of the wall; but in this case the filtering-partition is composed of alayer of glass wool o and of a disk of felt 7c, the latter being located below the former.

Fig. 4: shows another formof my invention in which the filtering-partition is formed by a layer of spun glass a at the upper part, an intermediatedisk offelt 7.9, and a lower disk of compressed charcoal fm.

It is easyt to clean -the two latter forms of filters in the same manner as the one rst describedY by causing a current of clear water to flow through the same in the inverse direction to that in which filtering usually takes place-that is to say, in the direction from h to g.

lt must be understoodithat the dimensions, v

forms, and materials of the constitutive parts of the filter shown in the drawings may be varied or modified without interfering with the principle ofthe invention.

I claim- .I v.

In a filter, the combination with the casing, the lower section thereof yhavingan,o utlet-tube at its lower portion, the upper portion of the section providediwith avertical 'upwardly-extended right-angular surrounding iange, a perforated gratingmounted on one portion of said ange with a suitable packing arrangedabove the same and coactling therewith, a rubber ring interposed between one portion of the packing and the lupwardly-extended wall of said lower section,

and a perforated grating mounted on the surl packings and gratings between the two seerounding upper-edge portion of said ring and tions of the casing, substantially as specified. the upper packing; of the upper section of In testimony that I claim the foregoing as the casing having an inlet-tube in line with my invention I have signed my name in pres- 5 the outlet-tube and the lower portion ot' said ence of two subscribing Witnesses.

upper section having a downwardly-extended l right angular surrounding flange to coact JULES EDOUARD CHARON' with the Vertical upwardly-extended ange Vitnesses: and With the upper grating on the ring and CAMILLE BLTRY,
